Plotly.express.imshow shows letters behind numbers when number is small (i.e 1.19e-07)

While doing a course in statistics I came across the issue where numbers approaching 0 appear as letters instead of their numerical representation when using imshow for heatmaps.

Such as ending in ‘f’ for ‘OP1 - OP4’ and ‘n’ for ‘OP3 - OP4’ as seen below. Is there a way to fix this? While not dealbreaking, since Dunn’s test doesn’t benefit from displaying values below 0.01, it is still weird and unexpected behavior…

首先，使用接近 1.19e-07 的值复现已报告的 Plotly.express.imshow 热力图行为，并将渲染出的标签与控制台输出进行比较。跟踪负责单元格文本的格式化路径；完成标准是小数值以数字而非字母显示，同时不影响正常的热力图标签。
